This invention relates to fireplaces and has special reference to oneparticularly adapted for outdoor use, the principal object of theinvention being to combine in a satisfactory and practical manner anopen fireplace and a heating oven.

Another object is to provide means for the most practical and efficientapplication of heat to the oven from fire otherwise utilized in thefireplace.

Still another object is to provide a simple and inexpensive unitembodying such a combination and which may be readily surrounded withbrick, stone, or the like, for decorative purposes.

Other objects and advantages of the invention will appear in thefollowing description thereof.

Referring now to the accompanying drawing, forming part of thisapplication, .and wherein like reference characters indicate like parts:

Figure 1 is a perspective view of a complete outdoor fireplace,illustrating one embodiment of the invention.

' Figure 2 is a transverse sectional view of the metal portion of one ofthe combined units.

Figure 3 is a rear end elevation of Figure 2.

Figure 4 is a top plan view of Figure 2.

In the drawing, i and 2 represent the side walls of the fireplace whichare of comparatively light sheet metal and supported for example as by aframe-like angle iron construction embodying the front corner members 3and 4 and like upright angle members 5 and 6 and which latter membersare at the back corners of the fire box portion of the unit. The sidewalls I and 2 extend rearwardly beyond the termination of the so calledfire-box and form the smoke chamber illustrated at l, and above which,and parallel with the top of the'grid 8, is installed the oven,indicated at 9. The smoke chamber 1 is also continued upwardly back ofthe oven 9 as at l0,

forming the lower portion of what ultimately 40 serves as the smoke orchimney flue. Within the lower portion of this smoke fiue is installedan inclined bailie indicated, at it for diverting the .heat units andsmoke towards the back of the oven 9, while within the smoke chamber andjust below the rearmost portion of the fire-box is installed the largerinclined baflle l2 for directing the smoke and heat units upwardlyagainst the bottom of the oven, thus providing novel and adequate meansfor utilizing as much as possible of the heat passing the bottom andrear wall of the oven.

A removable door of any desired design or description maybe installed asa closure for the. front of the oven, as indicated at l3, and the 55front corner angle of the sheet metal structure forming the oven may bemade to extend as illustrated at H to provide a convenient and betterappearance of the union of the ultimate covering of the unit, forinstance brick, stone, or the like,

and the sheet metal portion of the fireplace. 5 To this same end thefront corner angles 3 and 4 of the fireplace may extend laterally asbest shown in Figure 4 of the drawing. It is to be noted that the grid8is removable,

and that within the opposed side walls I and 2 l0 of the fireplace and apredetermined distance from the grate i5, are installed an extra pair ofhorizontally disposed angles I6 so that the grid may be readily-removedfrom the position shown in the drawing and placed upon the lower 1|angles 16, bringing the grid in closer proximity to the fire as forexample when the latter has burned down to a bed of coals and bettersuited for closer association with the particular come'stible beingprepared for consumption.

A similar-pair of angle bars are provided as at I! for the normalsupport of the grid, and also similar angles are provided as at I8 forsupporting the fireplace grates i5.

One particular feature that is contemplated .35 in such a structure isthat the angle iron frame portion is made of considerably moresubstantial and lasting material than that of the sheet iron coveringfor same especially that portion coming in direct-contact with the fireand which may 30 I become burned out or destroyed long before theheavier'frame portion, and this is of particular advantage in caseswhere the unit is well surrounded with either stone, brick, or othermore permanent material.

By the novel arrangement of bafiles II and I2 in the smoke chamber, itwill be noted that a substantial vacant area is provided back of each ofthese baflies, which areas function, in the event of a sudden downdraftof short duration, in o cushioning the downdraft and thus preventingsmoking of the fireplace.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:

1. An outdoor fireplace of the type described, 5 comprising an angleiron frame structure, an outer covering of sheet iron, a flre box, asmoke 'fiue communicating therewith, an oven intermediate of theuppermost rear end of the firebox and the smoke fiue therefrom, andbafile plates rearwardly of said fire box and within said fiue fordirecting the heat therefrom against both the bottom and back of saidoven.

2. In a combined outdoor fireplace and oven unit, an open fire box inthe front of the unit,

an oven back of said box and above same, a smoke flue beneath and backof said oven, and means within said smoke flue for directing the smokeand heat units against the bottom and back of said oven, said meanscreating a plurality of areas at one side thereof within said smoke fiuefor cushioning eflect therein in the event oi sudden downdraits, thusavoiding smoking 01 the fireplace.

3. A combined outdoor fireplace and oven unit comprising a horizontallydisposed open firebox in the front of the unit, an oven back or saidfirebox and above same, a smoke fiue extending longitudinally from therear of the firebox under the oven and upwardly back 01' said oven, andinclined bafl'ies within said smoke flue for directing the hot productsof combustion against the bottom and back 01 said oven, said bai'iiesextending in a direction to also prevent sudden downdrafts oi air insaid flue reaching said firebox and thus preventing smoking of thefireplace therefrom.
